Hey Rachel, great choice with the Interlogix 521B. Certainly! To install the Interlogix 521B smoke detector, begin by locating a suitable mounting location on the ceiling, ideally near the center of the room or hallway. Ensure there is proper clearance from walls and other obstructions. Connect the detector’s two wires to the corresponding wires from your security system, observing polarity. Use appropriate wire connectors and ensure a secure connection. Once connected, mount the detector onto the ceiling using the provided screws and anchors. Test the detector to ensure it is functioning properly, and then program it into your security system following the manufacturer’s instructions.
